Bunny Wabbots are a species of half-robot bunnies invented by Aperture Innovations, specifically ALPaCA. They can explode.

They are half-sentient, half-programmed. As such, they obey all orders given by any executive of the Cipher Syndicate. However, when not under orders, they frolic around, saying "Rabbit". They do not look robotic at all.

They do not explode unless ordered to. They are surprisingly difficult to kill. The explosion radius is programmable, but the blast radius cannot ever reach within a certain distance of HQ. Within this distance of HQ or Zerdark's Dimension, the explosion is completely disabled. A useful tactic in war is to send an inconspicuous, unkillable bunny rabbit to wander around the enemy army, then unleash an explosion.

Their eyes are also outfitted with Aperture Science Vital Observation Apparatus; in other words, if they are ordered to wander around an enemy base, they can record footage of it and transmit it back to Aperture.
